The best way to install the Mac OS version of this
software is by downloading the file:
   "Eq-Calc_java_Mac-OS.zip"
which contains Mac app bundles for DataBase and Spana.

If for some reason you need to use the non-system
specific zip-file "Eq-Diagr_Java.zip" on a MacOS system:
Copy the zip file to your desktop.  Double-click the
zip-file: it will then be un-zipped.

Now you may move the zip file to trash.  You may also
move to trash the subfolders "Eq-Diagr/Windows-files"
and "Eq-Diagr/Ubuntu-Desktop".

You can run the programs by double-clicking on the
corresponding jar-file.  You can create aliases by
ctrl-clicking on a jar file, and then you can move
the alias to the desktop, etc.
